Application filed February 18, 1907. Serial No- 358,000-

To all whom it may concern: I

Be it knownthat I, CHARLES M. SHEELEY, a citizen of the United States,residing at Kearney, in the county of Buffalo and Stateof Nebraska, haveinvented a new and useful Revolving Ball-Bearing VeterinaryOperating-Table, of which the following is a specification.

This invention relates to veterinary operating tables and has for itsobject to provide a rotary table or platform adapted to support a horseor other animal and capable of being adjusted at any desired angle orinclination to the supporting base so that the animal may beconveniently operated upon.

A further object of the invention is to provide an oprail combinedtherewith and which in connection with the'table constitutes a stallwhereby the animal may be readily led or guided to the operating tableand secured in position thereon.

A further object is to improve and strengthen the tical and diagonallydisposedbraces which form a support for the platform or table andsustain the weight of the horse or other animaL- A Afurtherobjectistoprovide the platform or table with a detachable sectionadapted to be removed when performing-certain operations on the animal.

A stillf urther object of the invention is to generally improve thisclass of devices so as to increase their utility, durability andefficiency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

In the accompanying drawings forming a part of this specification:Figure l is a front elevation of a veterinary operating tableconstructed in accordance with my invention showing the table invertical position and a horse in position thereon. Fig. 2 is a sideelevation partly in section of the same. Fig. 3 is a rear elevation ofthe table. Fig. 4 is a vertical sectional view showing the table inhorizontal position. Fig. 5 is a transverse sectional view taken on theline 5-5 of Fig. 4 and looking in the direction of the arrow. Fig. 6 isa perspective view of the table top removed.- Fig. 7 is a similar viewof the detachable section of the table removed.

Similar numerals of reference indicate corresponding parts in all of thefigures of the drawings.

The improved operating table comprises a stationary base or plate 5 anda movable or rotary plate 6, said plates being. provided with race ways7 for the reception of a series of antifriction balls 8 whereby theplate 6 is free to rotate without undue friction on the parts. Themarginal edge of the plate 5 is extended beyond the adjacent marginaledge of the plate 6, and secured l to the extended portion of the plate5 by bolts or similar fastening devices 9 is an annular retaining ring10 provided with a laterally extending lip 11 which engages acorrespondingly shaped recess formed in the adjacent edge of the upperplate 6 thus serving to lock said plates in engagement with each otherand prevent accidental displacement of the antifriction balls orrollers. The upper plate 6 is preferably centered on the lower plate 5by means of a pivot pin or bolt 12 which pierces both plates and isanchored in any suitable manner to the ground or other support,indicated at 13.

Secured to the revolving plate 6 is a table supporting stand preferablyconsisting of a plurality of brace bars having their lower ends securedto the plate 6 and their upper ends riveted or otherwise rigidlyfastened to spaced juncture blocks 13 and 14 which constitute bearingsfor a transverse shaft 15.

Secured to the outer faces of the bearing or juncture plates 13 and 14are substantially vertically disposed braces 16 preferably formed offiat metal and having their lower ends provided with laterally extendingarms 17 for attachment to the revolving plate 6, there being inclinedbrace bars 18 also preferably formed of flat metal and secured to theinner faces of the bearing plates 13 and 14 and having their flangedends 19 disposed one on each side of the pivot pin 12 and bolted orotherwise rigidly secured to the plate 6, as shown.

Secured to the outer faces of the bearing plates 13 and 14 on each sideof the vertical braces 16 are auxiliary braces 20 preferably formed ofangle iron and disposed at an inclination to the braces 16, there beingcooperating downwardly inclined auxiliary braces or bars 21 secured tothe inner faces of the plates 13 and 14 and having their lower endsprovided with perforated attaching arms 22 which over-lap and arerigidly secured to the revolving plate 6- in any suitable manner, as bybolts or similar fastening devices 23.

The bars or braces 16 and 18 are preferably arranged in alinement witheach other while the lower ends of the inclined bars 21 are disposed atright angles to the bars 16 and 18 and arranged on a line intersectingthe center of the plate thereby to produce a strong, rigid support forthe operating table 24.

The operating table 24 is preferably provided with longitudinalextensions 25 and is reinforced and strengthened by the provision oftransverse reinforcing ribs 26 provided with integral ears or lugs 27which over-lap the juncture or bearing plates 13 and 14 and are providedwith alined openings for the reception of the shaft 15, the latterforming a pivotal connection between the plates 13 and 14 and the tableor platform 24 so that the same may be tilted at any angle orinclination with respect to the base plate 5.

Depending from the bottom of the platform or table 24 are spacedsegmental racks 28 and 28 preferably secured to the bottom of theplatform by'attaching lugs 29 and reinforced and strengthened by one ormore lateral braces 30.

Secured to one of the inclined braces or bars 20 is a spaced plate orbracket 31 in which is journaled a stub shaft 32 having its inner endalso journaled in the adjacent brace 20 and provided with a pinion 33which meshes with a gear Wheel 34 carried by a transmitting shaft 35,the latter being extended through the vertical braces 16 and 18 andprovided with a terminal pinion 36 for engagement with the teeth on theadjacent segmental rack 28.

Secured to or formed integral with the gear-Wheel 34 is a pinion 37preferably of the same size as the pinion 36 and adapted to mesh withthe teeth on the rack 28 so that by rotating the terminal crank orhandle 38 on the stub shaft 32 motion may be imparted through theintermediate gearing to the pinions 36 and 37 and thence to thesegmental racks 28 and 28 thereby to tilt the platform or table 24 atany desired angle or inclination with respect to the supporting base.

One end of the shaft 35 is journaled in a connecting link 39 secured tothe shaft 32 and which serves to assist in preventing lateraldisplacement of the gear 34 and pinion 37.

As a means for securing the horse or other animal in position on thesupporting table 34 there are provided suitable attaching straps 40 eachhaving one end thereof secured in any suitable manner to onelongitudinal edge of the table or platform and their opposite endsextended over the opposite longitudinal edge of the platform forengagement With a winding shaft 41. The winding shaft 41 is journaled insuitable bearings formed in the segmental racks 28 and 28 and isprovided with a terminal crank or handle 42 by means of which thetension of the straps or belts 40 may be regulated at will. The adjacentends of the straps 40 are preferably secured to the winding shaft 41 byan auxiliary shaft or rod 43, said straps being coiled around bothshafts so that when the winding shaft 41 is operated the straps willbite on said shafts and thus prevent the same from slipping when thehandle 42 is rotated. Suitable hopples 43 are also preferably secured tothe table at points adjacent the opposite longitudinal edges thereof forattachment to the head and legs of the animal thereby to prevent theanimal from kicking. The table or platform 24 is also preferablyprovided with a detachable section 44 which may be removed so that thesurgeon may operate upon the horse without the necessity of bending overthe edge of the platform.

As a means for retaining the removable section in position on theplatform there are provided a plurality of locking bolts 44 adapted toengage corresponding recesses 45 formed in the platform or table 24, theinner ends of the bolts 44 being provided with terminal fin- .ger piecesor handles 46 which are slidably mounted of suitable hangers 52. Thehangers 52 are secured in any manner to a guard rail 53 which inconnection with the platform constitutes a stall and serves to guide theanimal to the operating table.

In operation the table is moved to vertical position by rotating theoperating handle or crank 38 after which the brackets 50 are fastened inthe lugs 48 and the guard rail 53 suspended from the free ends of thebrackets by means of the hangers 52. The horse or other animal is thenled into the stall formed between the guide rail and the adjacent faceof the table and the straps 40 passed over the body of the animal andthe latter clamped to the table by rotating the winding shaft 41, thehopples 43 being subsequently adjusted so as to prevent movement of thehead or legs of the animal, as best shown in Figs. 1 and 2 of thedrawings. The guard rail 53 and supporting brackets 50 are then detachedand the supporting table tilted laterally until it assumes a horizontalor substantially horizontal position, after which the detachable section44 is removed and the animal operated upon. it will thus be seen thatthe table or platform may be tilted at any angle or inclination to thebase plate 5 and said platform rotated upon the plate so as to presentany particular portion of the anatomy of the horse without the necessityof walking around the table.

If desired the segmental racks 28 and 28 may be formed with one or moreopenings 54 adapted to register with a corresponding opening 55 formedin one of the brace bars of the revolving stand thereby to permit theinsertion of a rod or bolt to assist in locking the platform in adjustedposition.
